Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to Chinese Patent
Application No. 201711476675.3 entitled DEVICE FOR REMOVING TOOL
JOINT EDGE BURRS OF WHEEL filed Dec. 29, 2017, which is
incorporated herein by reference for all purposes.
FIELD OF THE INVENTION
[0002] The present invention relates to the technology field of
removing burr from a joint between a casting face and a machined
face of a wheel, and specifically, to a device for removing tool
joint burrs between a casting face and a machined face at an outer
rim and a cap slot edge of a wheel.
BACKGROUND ART
[0003] A full coated wheel having the front not machined has a
circle of casting and machining face tool joint burrs at both the
outer rim and the cap slot edge after being machined, and the burrs
must be removed. With continuous improvement of customer's
requirements for product quality, burrs need to be removed. At
present, machining of an aluminum alloy wheel is completed by
adopting two lathes, i.e., first turning and second turning, and
such machining process results in coaxiality deviations between the
inner rim and the center hole machined in the first procedure and
the outer rim and the cap seam allowance machined in the second
procedure. The outer rim, the cap slot edge and the cap seam
allowance are all formed by the second turning, so if burrs are
desired to be removed, precision positioning should be implemented
by using the cap seam allowance coaxial with the outer rim and the
cap slot edge, the rotating center of a cutter is superposed with
that of a burr part, in this case, after the burrs are removed, the
outer rim and the cap slot corners are uniform, and the problems of
deviation and burr residue are solved. Based on the current
situation, this patent provides an automatic device for
simultaneously removing tool joint edge burrs from the outer rim
and the cap slot edge.
SUMMARY OF THE INVENTION

on the clamping guide rail and connected with each other via the
gear rack, the clamping cylinder is connected with the left sliding
plate, the four upright posts are symmetrically mounted on the left
sliding plate and the right sliding plate, and a clamping wheel is
mounted on each upright post. The electric cylinder is mounted in
the center of the movable plate II, the circle center measuring
sensor is mounted at the output end of the electric cylinder, and
the coordinate origin of the system is located on the center axis
of the sensor in an initial state. When a wheel enters the mobile
roller bed from a fixed transfer roller bed, the clamping cylinder
is started to drive the four clamping wheels to preliminarily
position and clamp the wheel. Next, the electric cylinder is
started to drive a probe of the circle center measuring sensor to
enter a cap seam allowance of the wheel, coordinates of the circle
center of the cap seam allowance are calculated via the coordinate
origin of the system, then the transverse motor is started to drive
the movable plate II to transversely compensate the coordinate
difference, the longitudinal motor is started to drive the movable
plate I to longitudinally compensate the coordinate difference, the
circle center of the cap seam allowance moves to the coordinate
origin of the system, the rotating center of the cutter system is
coaxial with the coordinate origin, the rotating center of the cap
seam allowance is superposed with that of the cutter system after
compensation, and because the cap seam allowance is coaxial with
the cap slot edge and an outer rim edge of the wheel, the rotating
center of the cutter is superposed with that of the burr part by
movement compensation of the clamped wheel driven by the transverse
motor and the longitudinal motor. This is a wheel precision
positioning system.
[0008] The inner cylinder is fixed directly above the frame, the
output end of the inner cylinder is connected with the inner mobile
platform, the inner motor is fixed on the inner mobile platform via
a mounting rack, the output end of the inner motor is connected

right blade, the rear blade and the front blade, are arranged on
the hollow disc, each of the blades are spaced 90 degrees from the
adjacent blades, the interior of the blade is a serrated step
cutting edge, and the four blades have an identical rotating center
and are used for removing tool joint edge burrs of the outer rim.
After the wheel is precisely positioned, the inner cylinder is
started to drive the inner mobile platform to move down, and the
sleeve moves down under the guidance of the guide keys, i.e., the
pyramid cutter moves down to an appropriate position according to
the height of a cap slot. Next, the outer cylinders are started to
drive the outer movable plate to move down under the guidance of
the guide posts; since the bearing seat is fixed on the outer
movable plate, the hollow shaft also moves down; and in the down
process, the guide keys stop, the guide key slots slide on the
guide keys, and the cutting edges of the blades contact burrs at
the outer rim. Then, the inner motor is started, the shaft can be
driven to drive the pyramid cutter to rotate, and the tool joint
edge burrs are removed from the edge of the cap slot. The outer
motor is started to drive the small gear to rotate, the small gear
drives the large gear to rotate, the inner wall of the hollow shaft
is connected with the sleeve via the guide keys, the sleeve is
matched with the inner bearing, and the outer wall of the hollow
shaft is matched with the outer bearing, so when the large gear

burr removing cutter system.
[0009] By adjusting the descending heights of the pyramid cutter
and the blades, tool joint edge burrs of wheels having different
cap slot diameters and different outer diameters can be removed, so
the universality is wider.
[0010] The working process of the device for removing tool joint
edge burrs of the wheel is: when a wheel enters the mobile roller
bed from the fixed transfer roller bed, the clamping cylinder is
started to drive the four clamping wheels to preliminarily position
and clamp the wheel. Next, the electric cylinder is started to
drive the probe of the circle center measuring sensor to enter a
cap seam allowance of the wheel, coordinates of the circle center
of the cap seam allowance are calculated via the coordinate origin
of the system, then the transverse motor is started to drive the
movable plate II to transversely compensate the coordinate
difference, the longitudinal motor is started to drive the movable
plate I to longitudinally compensate the coordinate difference, and

burr part after compensation. After the wheel is precisely
positioned, the inner cylinder is started to drive the pyramid
cutter to move down to an appropriate position. Next, the outer
cylinders are started to drive the four blades to move down to
appropriate positions. Then, the inner motor is started to drive
the pyramid cutter to rotate to remove tool joint edge burrs from
the cap slot edge, and the outer motor is started to drive the four
